Answer:
The answer is -37.
Step-by-step explanation:
1) Simplify 50-2 to 48.
48 ÷ 4 - [tex]7^{2}[/tex]
2) Simplify [tex]7^{2}[/tex] to 49.
48 ÷ 4 - 49
3) Simplify 48 ÷ 4 to 12.
[tex]12 - 49[/tex]
4) Simplify.
[tex]-37[/tex]
Therefor, the answer is Option C) -37.
what's is m when u are looking for x or y intercept
Answer:
Slope.
Step-by-step explanation:
mx+b
Answer:
Slope
Step-by-step explanation:
The equation of lines are normally formatted in "slope-intercept form"
(y = mx + b)
The b in the equation would be the y-intercept of the line.
The m represents the slope.
The x and y can be replaced with any x and y value from the line (if necessary)
The population of San Francisco was 776,733 in the 2000 United State Census, if the expected growth rate is 15%,
which is the best prediction of what the population of San Francisco will be in 2015?
Answer:
initial pop'n=776733
growth rate=15%
time= 15years
Then,

In a maths class the girl to boy is 7:5 If there are 20 boys how many girls are in the class
Answer:
Let the total no of girls be x
the number of boys=7:5
total no of students =20
now,
no of girls =7/5=x/20
or, 20*7=5x
or 140=5x
or,x=140/5=28
therefore the number of girls =28
A publisher sells 10 to the power of 6 copies of a new book.
Each book has 10 to the power of 2
pages.
How many pages total are there?
Answer:
100,000,000
Step-by-step explanation:
10^6= in this case, just add 5 zeros to the 10. each zero multiplies the number by 10
1000000 books
10^2 pages per book- 100 pages
1,000,000 x 100= 100,000,000

What is the missing polynomial ?-(20-4x5x^2)=20-7x^2
Answer: [tex]-2x^2-4x+40[/tex]
Step-by-step explanation:
Suppose the missing polynomial be f(x)
So, we can write
[tex]\Rightarrow f(x)-(20-4x+5x^2)=20-7x^2\\\Rightarrow f(x)=20-7x^2+(20-4x+5x^2)\\\Rightarrow f(x)=-2x^2-4x+40[/tex]
Given isosceles right triangle CDE with m∠D = 90, sin C = sin D
Answer:True
Step-by-step explanation:
Given
[tex]\angle D=90^{\circ}[/tex]
For isosceles triangle , CD=DE (x=y)
from figure,
[tex]\sin C=\dfrac{y}{H}\\\\\sin D=\dfrac{x}{H}\\\\\text{CD=DE}\\\\\therefore \sin C=\sin D=\dfrac{x}{H}=\dfrac{y}{H}[/tex]
Thus, the given statement is true

y
∝
√
x
If
y
=
45
when
x
=
81
find,
y
when
x
=
225
Answer:
y = 75
Step-by-step explanation:
Given that:
y [tex]\alpha[/tex] [tex]\sqrt{x}[/tex]
⇒ y = k[tex]\sqrt{x}[/tex]
where k is the constant of proportionality.
When y = 45, x = 81, then;
45 = k[tex]\sqrt{81}[/tex]
45 = 9 k
k = [tex]\frac{45}{9}[/tex]
= 5
k = 5
So that,
y = 5[tex]\sqrt{x}[/tex]
the value of y when x = 225 is;
y = 5[tex]\sqrt{x}[/tex]
= 5 x [tex]\sqrt{225}[/tex]
= 5 x 15
y = 75

Answer:

Step-by-step explanation:
Hello There!
First things first, we should find the rate of change / slope
given two points we can find the slope by using the slope formula which is
(let m be slope)
[tex]m = \frac{y_2-y_2}{x_2-x_2}[/tex]
To find the slope all we have to do is plug in the points
(1,5),(2,10)
remember the first numbers in an ordered pair are the x values and the second numbers are the y values
we also plug in the points of the second ordered pair first so
[tex]m=\frac{10-5}{2-1} \\10-5=5\\2-1=1\\m=\frac{5}{1} or5[/tex]
Knowing the slope we can create an equation to find the x value (a)
y=5x
given the y value we plug in y and solve for x
15=5x
divide each side by 5
15/5=3
5x/5=x
we're left with
x=3
so we can conclude when y =15 x = 3 therefore 3 is your answer
